The front mrt of tlf portion ti oi" the presser foot. turned non n.' d :is fit 8. :is shown in dotted lines in ligi. l. und in front, View in Fig. 8. The central portion G of thepresser foot is rigid with the presser bar 3, and moves up :ind down therewith to accommodate varying tliirknr-f-ises ot fabric. 'lie shank portion 9 oi' the presser foot el, is .slotted to reeei ve the with portions 10, 10. which extend along sido of the portion G. The side portions 10, it? nre duplicates o euch other, and n desvriptit., of one willv answer for the other. llerh or" the, side portions 10, carries :i pin t which extends up tliroligl'i an opening in e shank 9 sind fi spring 12 secured to the :ink rests upon the upper end of the pin A stud 13 passes through a slot in the members 10. es shown in dotted lines in Fig. l. and serves to limit the downward movement of the members 10, through the influence of the spring 152. The forward part of the central portion 6 tapers outwardly as l i n 'l'hiiii-wiser hor fl. reriproentes in the head shown in Fig'. The side portions l0, 10, are also tapered outwardly as shown in this ligurer and as also shown in Fig. 8 of thel drawings.

The outwardlyv taperingr portions of the parts 10, and the up *ardly tapering portion of the part ti, form a wide mouth to receive the folded strip of fabrio. The machine herrin designed is especially adapted for foldingr narrow strips of fabrics for making what is known in the art as belt loops. The strip of fabric at each side is folded. and its folded edges are brought substantially togetlier as shown in Fig'. if). wherein the fabrir is indirated at l.

'lho edges of the fabrio herein shown lie substantially.' in the central part of the folded portion of the fabric. Two lines of stitehing: it. 1l are than passed through the folded l"trip whirh lines of stitchin are ronneeli-d by cross stitching 15, Whitt. lies aeross the meeting edges of the folded strip, thus covering the. saine.

lin order to properly fold the short strips of fabrn` the folder lo is provided. whit-h Consists of a shank portion l? set-ured to the bed plate in the usual manner. Said folder 1G. eonsists of a raised olor-hY 154, to whieh is secured a forwardly projeetingr supporting: tongue li. around whirh the strips` of fabriil may be folded. The tongue l?? at its forA ward end is suliiported by a rib Q0 which is secured to the base portion of the folder. ln order to fold the .strip of fabric around. the tongue 19. the folder is provided with outwardly, upwardly and inwardly curved side portions "ll, 2i. which gradualiy taper toward the delivery end of the folder. rthe upper edges of the side, portions 2l. .l. are widely spaced, and are provided with projeeting portions Q27 215. near the delivery end of the folder7 whirh substantially bridge said delivering end.

The widely spaced side portions allow very short strips of fabric to be fed to thc folder as acoess may he had to tho strip throughout a greater portion of the length of the folder. The folder is provided at its receiving,r end with the guiding member lli` whieh has upwardly turned edges 124. fornr inf.r a guiding rhannel for the strip of fabric.

The forward end of the side portions 2l are extended to form projecting membersv 25, 25. Said members 25. are lorated within the mouth portion of the presser foot. and serve as a guiding means for the folded strip of fabrie after leaving the folder, so that the width of the folded Strip may be maintained aeeurately until said strip has been reeeived by the presser foot and stitehed. The folder is preferably of such a width that the folded strip is of the saine width as the portion 6 of the presser foot, so that the side portions l0 of the presser foot will extend down on each side of the fouled strip,

'guide is rut away at the bottom so as to avoid an interference between the folder and thi4 feed dog. while the folding tongue lt? and the projecting members extend over the fred dog so as to properly hold and guide the fabrie until it has well entered beneath the presser foot of the machine.

llaving.r thus particularly describei my invention. what I claim as new and desire to serure b v Letters Patent is1-- l. sewing' machine including in combination. .spaced needles, a presser foot having a guiding ret-ess on its under face for a folded strip of fabric, and a folder forl fold-4 ing the edges of said strip underneath the body portion of the srip so that said edges substantially meet centrally of the folded strip. .said folder comprising a tongue arourul u hieh the strip is folded. said tongue at the forward end thereof beingv supported by a rib extending; longitudinally of the folder. and `side portions which `extend manual the outer edges of the tongue for foldingr the edges of the strip around the .said touffue.
